GRAIN GI-IUTE.

Application filed June M,

T 0 all whom it may concern.

Be it known that I, JAMns lVEs'rFALL, a citizen of the United States residing; at

tate of Montana, have invented certain new and useful Improvements in Grain Chutes, of which the following is a specification.

This invention relates to grain chutes and more particularly to an attachment adapted to be disposed between the hopper bottom and a grain spout somewhat in the nature of a pipe connection to prevent the loss of grain being conveyed.

In actual practice it has been found that when the grain chute is turned to the left or right that a small opening is left between the bottom of the hopper and the upper end of the chute permitting a certain quantity of grain to fall on the separator or on the ground which of course is a total loss, and it is the object of this invention to introduce a novel and improved connection between the hopper and chute whereby this loss is prevented.

One of the objects of the invention resides in the provision of a sectional coupling or chute connection with the bottom of a hopper permitting a certain amount of freedom of movement of said sections on their pivots when the grain chute is swung to the left or right and at the same time preventing any of the grain from dropping on the separator or the ground during such movements.

Another object of the invention resides in the construction of a sectional pipe connection for a hopper and grain chute which shall be of such design as to accommodate various size grain spouts, and one in which the parts are extremely simple in construction, easily assembled, highly efiicient in operation and use, practical and capable of being manufactured at a minimum expense.

With these objects in view and others which will be manifest and suggested as the purpose and nature of my invention are revealed in the following specification and drawing wherein I have shown a preferred embodiment thereof, 1

Figure 1 is a view partly in section showing the invention as connected to the grain v chute and the bottom of the hopper,

Fig. 2 is a perspective view of one of the sections of the connection, and,

Fig. 3 is another view of the bottom section of the connection.

1921. Serial No. 477,430.

Referring now to the drawings wherein like parts designate corresponding parts throughout the views, 5 designates the usual type of hopper which receives the grain from an elevator (not shown) and 6 designates the grain chute between which I have disposed my novel and improved con nection subsequently to be described in detail. Disposed at the bottom of the hopper, I have provided a discharge spout 7 preferably swivelled to the bottom of the hopper permitting the chute 6 to be turned to the left or right during the operation of load ing as is well understood.

The novel and improved connection above referred. to primarily consists of a curved, segmental top section 8 and a curved segmental bottom section 9, the latter being formed in the nature of a scoop, the top or neck portion 10 of the section 8 having bolt holes 10 at its ends whereby said section may be pivotally connected to the discharge spout 7 as shown at 12, on each side of said spout. In the same manner, the bottom 9 is provided with boltholes 13 at its upper end or neck portion and also pivotally mounted to swing on the pivot 12above referred to. Each of the sections 8 and 9 are substantially semi-cylindrical in form, the bottom section overlapping the top section shown at 14 thus permitting the pipe connection to accommodate various size chutes which may frictionally engage the lower ends of the said sections or be clamped thereon in any well known manner. By reason of the pivotal connection and mounting of the top and bottom sections, it will be readily understood that a certain amount of free play may be had between the grain spout 6 and the hopper, that is to say the bottom section 9 may swing on its pivot being in sliding engagement with the spout 7 to permit a certain amount of vertical movementof the grain spout above referred to.

The upper end of the body portion or spout 6 is reduced at the opposite sides as indicated by dotted lines at 15, and the pivot pins 12, only one of which is shown in Fig. 1 are extended through the three portions 8., 9 and 15.

By reason of this construction, it will be readily apparent that the sectional con nection betwen the spout and hopper is such as would prevent any grain from falling or being discharged on the ground and at the same time permits the spout 6 to be rotated to the left or right or slightly swung upwardly as occasion may require.

In the accompanying drawings, I have illustrated my invention embodied in one form by way of example, and which in practice has been found to be highly satisfactory 1n obtaming the desired results. It Wlll be obvious however that other embodiments may be adopted and that various changes in the details or construction may be resorted to by those skilled in the art without departing from the spirit. and scope of the invention. It is furthermore understood that the invention is not necessarily limited or restricted to the precise elements shown except in so far as such limitations are specified in the subject matter being claimed.

Having shown and described the invention what I new claim as new and desire to secure by Letters Patent of the U. S. is 20 In an apparatus of the class described, a hopper device including a discharge portion, a curved spout section rotatively coupled to the hopper discharge, a curved top section and a curved bottom section overlapping by their confronting edges and pivotally united and pivotally coupled to the rotative spout section, and a conductor spout inclosing the overlapping top and bottom sections and formed with reduced side portions pivotally coupled to the curved spout section and the curved segmental sections.

In testimony whereof, I aflix my signature hereto.

JAMES WESTFALL.
